SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 410,279, dated September 3, 18849.

Application filed November 12, 1886. Serial No. 218,703, (No model.)

.To a/ZZ whom it may concern.- Be it known that I, JOHN JAMnsHnYwooD,

of Fall River, in the county of Bristol and' State of Massachusetts, have invented a new and useful Improvement in Supports for Spinning-Spindles; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a description thereof.

The invention consists in mounting the spindle within a step or bearing, which bearing is mounted and supported so as to be revoluble within a hollow `case or bearing, as hereinafter described and claimed, whereby the friction caused by the revolution of the spindle will be distributed so that the spindle can be run at a higher speed.

The invention also consists in certain features of construction and arrangement described and claimed. g In the accompanying drawings, Figure 1 is a view representing the end of the drivingcylinder and a spindle arranged in accordance with my invention, the spindle and its connections being shown in central vertical section. Fig. 2 is a plan view of two spindles and a portion of the driving-cylinder, two systems of banding being represented. Fig. 3 is a plan view of two spindles and a portion of the cylinder, showing a modilied system of banding. Fig. 4 is central vertical section of a spindle and the parts in which itis mounted, two revoluble steps or bearings being employed.

Referring to the drawings, 10 is the steprail of a spinning-n1achine, and 12 is a hollow supporting-case mounted therein, closed at its lower end, and having a lian ge at its upper end, which rests upon the rail, the case being secured to the rail by a set-screw 1,3.

11 is the driving-cylinder.

Within the case 12 is stepped the revoluble tubular spindle-bearin g 14, which is provided with a whirl 15, and preferably with an up- Wardly-extendin g sleeve 16. Into the bearingtube 11i is stepped the pintle 17 of the livespindle 1S, which is furnished with a Whirl19, and the upper portion of said bearing-tube acts as a bolsterbearing for the spindle.

In banding the spindle a single band such as is shown in the upper part of Fig. 2 may be employed, which band passes about the Whirl 19 and about the cylinder 11, or, as shown in the lower portion of Fig. 2, the band may be carried about the whirl 19, then to and about the cylinder 11, then back and about the whirl 15, then about the cylinder again and the ends of the band joined; or, if deem ed advisable, instead of driving a single spindle by a single band, as shown in Fig. 2, one band may be used to drive two spindles, as shown in Fig. 3, by carrying the band from the cylinder about one of the whirls 15, to and about the other whirl 15, back and about the whirl 19 on the rst spindle, then about the whirl 19 on the second spindle, thence about the cylinder to connect with the other end of the band. I'Vhen the spindle and the revoluble step 14. are banded, as shown in the lower portion of Fig. 2 and in Fig. 3, the number of revolutions of the step 14 relatively to the spindle will depend upon the 'size of their respective whirls. If the whirl 15 be twice the diameter of the whirl 19, the bearing 14. will revolve about half the number of times that the spindle revolves. So, if the spindle be revolved twelve thousand revolutions per minute, the bearing 14. willturn six thousand revolutions in the saine time, and the friction on the spindle will be only equal to that caused by six thousand revolutions per minute in a stationary bearing.

Although I prefer to employ but one revoluble step or bearing, I may under certain circumstances use two of such bearings, one being supported so as to revolve upon the other, thus still more distributing the friction. The arrangement of two revoluble bearings is shown in Fig. 4, where the Vspindle-bearing 14 is stepped within a revoluble bearing 20, which is furnished with a 4whirl 21, and the latterbearingis steppedwithin the supportingcase 12. With this construction the friction caused by the revolution of the spindle will IOO Ysaid bearing, a driving-band common to the two whirls, and means, substantially as described, for driving the band, substantially as set forth.

3. The combination, with the supportingoase 12, of a spindle-bearing 14, stepped into said case and having a Whirl 15 and an upwardly-extending sleeve 16, and the spindle 1.8, extending down through said sleeve and whirl and stepped at its lower end into said bearing and having a whirl 19, surrounding the sleeve 16, substantially as set forth.

4. The co1nbinaton,with the hollow supporting-case 12, of the bearing 20, stepped therein, the spindle-bearing 14,stepped within the bearing 20, and the spindle 18, having a whirl and extending down into 'and stepped within the bearing 14, substantially as set forth.

5. The rotating or live spindle and the tube containing bolster and step bearings for the spindle and provided with a whirl whereby the said tube may be rotated, combined with a ease or holder for the tube and a step for the tube, substantially as set forth.

6. The spindle, the bearing-tube provided with a Whirl, and a step for the tube, coinbined with means to rotate the said spindle and bearing-tube, substantially as set forth.
